Hi, interesting question, not so easy - this has possibly consequences for recycling options (more complicated? Less compatibility with other plastics without the additive?), and of course on biodegradability - where you need to model the possible biodegration (which is maybe more a theoretical option now, it could help to address littering, maybe, but it is also not straightforward to really achieve biodegration for plastics, to my understanding), and littering itsself is typically not considered in the LCA. Of course you should consider the impacts of producing the additive, in the LCA.
